422 REVISION, OF FAMILY SATURNIID^. 



to describe the genital structure, but I should imagine it to resemble 

 splendidus rather than cecropia in this respect. 



The larva of this species is not known, but the cocoon and pupae are 

 described by Mr. Tepper (L c. supra). 



The specimens thus far known are all from Southern Arizona.

Male : Black or smoky ; a whitish band on collar and at base of thorax. 

 Abdomen with a pale stigmatal band iuclosing darker spots. Pri- 

 maries with a creamy white basal band, outwardly curved and angulated 

 on the median vein. An angular whitish mark at the end of and extend- 

 ing across the discal cell. A broad,, even white band, outwardly edged 

 with ferruginous and dotted with black scales. The outer margin is 

 yellowish gray, brightening inwardly to a creamy white where it is 

 limited by a sinuate black line, which extends from vein 6 to the hind 

 augle. Within this line is a light yellow shade interrupted by the 

 black veins, and between each vein by a spur from the lunate black 

 spot which bounds the ferruginous space beyond the white line. Of 

 these spots the 3d, 4th, and 5th from hind angle have centers of bluish 

 scales, the centers increasing in size upwardly. In the apical region 

 beyond the white band is a pearly blue shade in which is between veins 

 G and 7 a large round black spot, preceded by a black cresent which is 

 mai gined with blue scales, and succeeded by an irregular deep red brown 

 blotch which extends to the pale outer space. Between veins 7 and 8 

 is a 3-shaped white mark, the central part of which tou ches a pyriform 

 deep brown si)o t. Secondaries with a pale crescent at the end of cell ; 

 a broad white outer band, similar to and joining that of the primaries, 

 followed by a ferruginous shade which is irrorate with light blue and 

 black scales. Beyond, is a mouse-gray marginal space which is crossed 

 by a lunate black line, w ithin which is a series of oval black spots. 



Female: "Head and thorax dull black, collar iiinkish white; a tuft 

 of red hairs at base of thorax ; abdomen dull black with a double row 

 of lateral red stripes inclosing small black spots ; l%s dull black. 

 Wings dull black, with the costa on primaries slightly inclining to gray; 

 no basal bauds, nor light abdominal margin to secondaries ; the spots in 

 the median fields aresmall, and plain white with no edging; onprimaries, 

 they form a triangle, and on secondaries simply a bar. A wide band 

 of white near the outer margin runs through both wings and makes a 

 decided curve toward the apex on primaries, where it is tinged with 

 pale fulvous; beyond this band, outwardly, the color on primaries is 

 grayish black, lighter toward the outer margin ; the apical spot is black, 

 surrounded by dark gray, then bordered inwardly by a bluish crescent 

 edged with black, and outwardly by a dull reddish shadiug; between 

 each of the veins below the apical spot, and bordering closely on the 

 white baud, is a bluish crescent corresponding to the apical one, filled
